EC 220.127.116.11 - Memapsin 2
IntEnz Enzyme Nomenclature
β-site Alzheimer's amyloid precursor protein cleaving enzyme 1 (BACE1)
β-site APP-cleaving enzyme 1
membrane-associated aspartic protease 2
β-site Alzheimer's amyloid precursor protein cleaving enzyme 1
- Broad endopeptidase specificity. Cleaves Glu-Val-Asn-LeuAsp-Ala-Glu-Phe in the Swedish variant of Alzheimer's amyloid precursor protein.
Suggested to be the major "β-secretase" responsible for the cleavage of the β-amyloid precursor protein to form the amyloidogenic β-peptide that is implicated in the pathology of Alzheimer's disease. In peptidase family A1 but is atypical in containing a C-terminal membrane-spanning domain.
